Python: Functions With Varying Numbers of Parameters

In this lesson, we'll take a look at the max() function and see how it works in Python.

Some functions are a little different in that they take a variable number of parameters. And we're not talking about default values. Check out this example:

max(1, 10, 3)  # 10

In the above example, the max() function finds the maximum value among the passed parameters. To find out how many parameters can be passed to the input, you need to look at the documentation этой функции. Там мы увидим такую конструкцию:

max(arg1, arg2, *args[, key])

This means that max() takes two or more parameters as input:

max(1, -3, 2, 3, 2)  # 3

If the function finds several parameters with the maximum value, then it'll return the very first one.


Calculate the minimum number (not mentally) from 3, 10, 22, -3, 0 - and display it. Use the min() function, which works in the same way as max().

The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

  • Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨

Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.

My code is different from the teacher's one 🤔

It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.

In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.

I've read the lessons but nothing is clear 🙄

It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.

By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.
